“…Metallic nanostructured films incorporated into optoelectronic devices such as photodetectors have attracted attention for their ability to support localized surface plasmon polaritons (LSPPs), which can enhance optical absorbance, internal electric field, and ultimately device performance. − Such films can also act as a device electrode, making them a cost-effective, flexible, high-performance alternative to the commonly used indium tin oxide (ITO), which is expensive and brittle. , Plasmonic enhancements provided by nanostructured electrodes can be engaged by light of varying wavelengths depending on the geometry, periodicity, and material of the nanostructures. ,− This provides a mechanism for tuning and enhancing the spectral photoresponse of optoelectronic devices, making plasmonic nanostructures attractive for a wide variety of applications including solar cells, fiber-optic communications, displays, disk drives, motion sensors, filter-free imaging, flame and missile detection, environmental monitoring, and industrial process control. − …”
